WKSE signed on as WHLD-FM in 1947. It changed its call sign to WZIR in 1980, WRXT in 1984, and the current call sign in 1985. It currently runs a Top 40 format. Much of its playlist overlaps that of sister station Star 102.5 at times (ironically, the 102.5 frequency was a CHR competitor of WKSE in the late 1980s and early 1990s as WMJQ "Majic 102"). WKSE competes with longtime rival, 2Day FM 105.1 (formerly 2Day FM 105.1/101.1), which has a very similar format. Currently, the ratings for WKSE is higher than 105.1 2Day FM in the Buffalo and Niagara Falls region, according to Arbitron.
